Answer to Question 2:

When the exchange rate is fixed, the domestic money supply is endogenous.

True or False?


The answer is true. By endogenous, we mean that the level of the variable is determined within the equilibrating process by the equations of the model. This is in contrast to exogenous variables, which are determined outside the model independently of the process of achieving equilibrium. Under fixed exchange rates domestic equilibrium is determined by the condition of goods market equilibrium in conjunction with the world interest rate and other rest-of-world variables independently of monetary factors. The authorities are then forced to produce a money supply that will maintain asset or portfolio equilibrium, given the equilibrium levels of output and/or prices. The nominal money supply is thus determined within the model's equilibrating process.
